Re: How to build your own off grid inverter

Do you have schematics for this? EDA files? I'm trying to find good designs to learn from. Thanks! The attached PDF for the EG8010 will give you some good information to help understand. Section 6.6 is basically what my inverter is but has had modifications (Totem pole drivers in addition to the IR...

Re: How to build your own off grid inverter

I have files in PCB design files in Designspark and can make Gerber files. However, I know many don't like this but the PCB is my schematic.

Re: How to build your own off grid inverter

Is that a version of the ozinverter? Thanks for posting :) Hi Damien, love your videos. This is my design based on the work of Oztules who designed what is sold as the Ozinverter. I had originally used the Ozinverter design but had lots of issues and added Totem Pole Drivers to the Power PCB of my ...

How to build your own off grid inverter

I noticed some time ago Damien asked me to share what I have done, unfortunately, I did not have email notification setup and had not been here for a long time. I have built several of these inverters and sold many PCBs to others to do the same via https://www.thebackshed.com For around $500USD you ...

Re: Damien's Off Grid Home Project

I have been running my own home built off grid inverter for 6 years now, runs at up to 8KW continuos with a 48V 775AH forklift battery. Also have 2 grid tie inverters connected to it so most of the day the off grid inverter is running backwards charging the battery from the GTI's. I also have a Ardu...

Re: OzInverter Build

I have built my own inverter almost the same but with improvements such as Totem Pole Fet drivers. It has been running my house for the last 6 years. It is capable of 8KW continuous and can start a 5KW induction motor. Re Prius inverters, they may be great at 300 VDC but the IGBTs are not so efficie...

Re: Off Grid Power Inverter from Gen 2 Prius inverter

In this analogy, the coffee table is Johannes' code that can drive a vehicle in a sensible manner. And the firewood is making ordinary 120v 60z with no variation or complexity. I already have code that I am using ATM to drive Inverters that I have built already. One thing I like about the Prius Inv...

Re: Off Grid Power Inverter from Gen 2 Prius inverter

That will be awesome if it could be possible to get 3 pahse AC from prius inverter Well you certainly can. It drives 2 different 3 phase motors. It's just a matter of making the software dumb enough. 60hz and whatever voltage no matter what. Done. Right now it's being used as a speed controller so ...

Re: Off Grid Power Inverter from Gen 2 Prius inverter

I love your idea and I'll be following this thread. These inverters in the Prius are so powerful and very inexpensive. I'm off-grid and I turned my Prius into a backup generator when I'm not driving. I'm still exploring the best option for using it this way. Now I've got four of these cars and it s...

Re: Off Grid Power Inverter from Gen 2 Prius inverter

I am only interested in off grid, here and in many countries connecting non approved equipment to the grid can result in very large penalties. There was a case in USA where someone lost their house as a result of it. With my current setup it is also using grid-tie inverters, they synchronise with th...

Re: Off Grid Power Inverter from Gen 2 Prius inverter

The Prius Inverter is a VFD already, with the right software you could control a 3 Phase AC motor as that is what it does in a car. VFD's are readily available and have lot's of features such as the main one of variable speed, a standard 3 phase motor will run happily in a range of 50 to 100% of it'...

Off Grid Power Inverter from Gen 2 Prius inverter

First of all, is this subject okay here as the forum seems to be all about EV's? I run my house off of a home built 8KW 48VDC to 240VAC Inverter that I have built myself. However, I was wondering if anybody has attempted using a Prius Inverter to do this? My first thoughts were to use the MGM2 inver...
